I just got a call from a girl who wants a layered cookie cake in place of a wedding cake, but I think she wants it to look like a wedding cake... I told her I would do some research and get back to her, but other than personalized individual cookies, I haven't seen anything that I would consider to be nice enough for a wedding. Has anyone made a large, layered cookie cake? Any ideas for me on how to do it and/or make it look nice. She also mentioned not having icing, so I don't know what direction we will go, but I want to gather my options before I talk to her again.
Seems like I always get the people who want something different!!! lol..... thanks for your help! 
I have done one like this (I think) for a kids' b-day.
In the round cake pans I made deep dish chocolate chip cookies and the same in sugar cookie (snickerdoodle)
I layered 3 c-chip together with ganache with more ganache on top, but not frosting the sides. The snickerdoodles had a layer of cinnamon-flavored cream cheese icing in between.
Unless she is wanting single layer, I imagine you would have to get her to pick out something to glue it all together, even if the top and sides were not iced, but just decorated/topped with flowers/etc.
Neat idea though, especially if the bride is not a fan of cake.
It would look a bit like a napoleon and using cake pans rather than free-hand cookies gives you even layers, and you can even trim all but the top layer of bumps or high edges.
Oh--whipped cream/light whipped icing don't work well, as the cookies are darn heavy! 
Learned that quick!
Wish I had a pic of it, but so many of my photos are stone age film. 
I think this is what she is talking about!!!This is Martha Stewarts version but can easily be replicated..Make sure you charge enough though...very very time consuming!!!
HTH 
Someone on here did it with 3 large cookies iced to look just like a cake. Couldn't tell any different from the outside. I don't know how you could support it to stack.
Check the galleries, if I can find it I will post.
I am sure you could decorate it just like a wedding cake. I think it would be a lot of fun and a nice alternative for those that are not a fan of cake!
I walked past Mrs. Fiels in the mall yesterday, and they are making cookie cakes like you described. I checked their website, but there are no pics of what I saw
